Knock is a UK producer of world-class hand grinders. The Aergrind is their preferred model for travellers as it's designed to fit inside your Aeropress. With flat, 38mm, black steel burrs you can grind excellently for Ibrik/Cevze style coffee, all the way through espresso, filter and French press. All grinders from Knock have a handy top dial adjustment.
The Aergrind features a single piece precision machined body, made from high grade aluminium and paired ball bearing sets (2x2) for both shaft and knob.
Knock's custom treatment of the burrs makes the surface hardness of the metal up to 85% stronger than stainless steel. This ceramic case hardening process is not a coating, but a treatment that changes the composition of the surface layer of the steel and is known for its supreme durability.

We ship every Monday, Wednesday & Thursday with DPD Parcel Service. We’re pretty fast in completing and shipping your orders. But just to be on the safe side it’s best to take in account a total delivery time of 2-5 days.
Roasting & Freshness
We aim to deliver fresh but rested coffee you can dig into right away. That means most coffee we ship is 2-10 days old. If you prefer the hyperfresh stuff, let us know in the order notes box on your cart page. Our coffees taste best 1-6 weeks after roasting but can be enjoyed for up to 3 months or more if vacuum packed and/or freezed.
